NAT (in QEMU/KVM) and WSL2 doesn't have internet, but host does

Question

I've tested in 3 differents PC in my network, with Fedora, Arch and Windows

None of the guest OS have Internet, nor VirtualBox, QEMU/KVM, and WSL2, but when I use brigde networking or MacVtap option in VirtualBox or QEMU, the guests magically can connect to the internet.

Why is that? My problem is that, WSL2 doesn't have an elegant and easy option for brigde networking, so I'll try to fix the problem for the root.

I'm in Windows 11 in my pc now, how can I have access to the internet from my guest OS's using NAT (Network Address Translation) in windows? (AKA wsl2) It has something to do with my router? I've read somewhere that it can be that my router has disabled the option for multiple IP's on the same MAC address or something, DNS?, DHCP?, I've searching for hours by now and nothing fixes my solution, help.

UPDATE :

YES!! I was right, It's my modem/router configuration. Here's what I've done, I've connected a TP-LINK TL-WR850N Wireless N Router to my main modem/router (Through the WAN Ethernet Blue port) and connected the TP-Link router to my main pc with Windows.

Windows has internet, and WSL2 Ubuntu too, when I ping google.com and update/upgrade the packages, I've searched in the TP-Link configuration and found an option called NAT Forwarding that grabbed my attention.

NAT Forwarding

I've enabled UPnP in my main router, still doesn't work, but It can be advise that you activate it in case of a problem.

And activated IGMP in my main router too, The TP-Link has it enabled by default and for I can see, I can't deactivate it LoL.

IGMP option in TP-Link

Still, no internet in WSL2 Ubuntu, but I guess it's a progress....

I'm going to clarify that, I'm not going to use the TP-Link router and call it a day, I'm paying for 200Mbps for Fiber Internet, and this little router (My ISP send it to me for free, I'm using it for another purpose now) limits the internet speed of my pc to around 90Mbps. The TP-Link has only 10/100Mbps ports, all of them, so yeah, thats a no no.

Thanks for the help.
